To convert a street address to its corresponding latitude and longitude, go to the website LatLong.net and click on the menu item Address to Lat Long. Enter the full street address, including the city name and country code, and the website returns the latitude and longitude associated with that location, the GPS location of the address, and a map plotting the position.
Latitude lines, also known as parallels since they are parallel and equidistant from each other, run horizontally on a world map. Each degree of latitude measure approximately 69 miles but varies slightly since the Earth is not a perfect sphere. The equator is 0 degrees latitude. Degrees of latitude increase from 0 to 90 as they move away from the equator. The North Pole is 90 degrees north latitude, and the South Pole is 90 degrees south latitude. Alternatively, latitude is a positive number in the northern hemisphere and a negative number in the southern hemisphere.
Longitude lines, also known as meridians, run vertically around the globe. The lines converge at the poles and are farthest apart at the equator, about 69 miles from each other. Zero degrees longitude is located at Greenwich, England. The degrees continue 180 degrees to the east and west, and they meet to form the International Date Line in the Pacific Ocean. Alternatively, longitude is a negative number as one heads west from Greenwich and a positive number as one heads east.
Every place on Earth has a unique latitude and longitude associated with it.
Scientists once divided degrees of longitude and latitude into minutes and seconds, but today typically express them as decimals.
